Abstract
A television image projecting system for projecting a television image on a screen at a magnified scale includes a plurality of projector systems of different colors sealed in one cathode ray tube. Electron beams of the projector systems are simultaneously deflected by a common deflecting device and spherical reflecting mirrors of the projecting systems are disposed closely to each other to partially overlap each other, and the overlapped portions are removed. The plurality of projector systems are in-line arranged, whereby color-stability and color balance over a wide range are attained.
